It was a clean sweep for Oregon and almost one for Oregon State on Wednesday during the first day of men's match play at the 101st Oregon Amateur at Willamette Valley Country Club in Canby.

Andrew Vijarro, Jack Dukeminier and Isaiah Telles, who helped the Ducks finish a school-best third place at the NCAA Championships earlier this month, all won their first-round matches to advance to Thursday morning's round of 32. The quarterfinals will be played Thursday afternoon.

Vijarro, the defending champion and stroke play medalist, beat George Hale 6 and 5. Dukeminier beat George White 4 and 3, and Telles defeated Jason Wood 4 and 3.

Robbie Ziegler and Jack Paton, who are on coach Casey Martin's UO roster, also won Wednesday, giving the Ducks a 5-0 day.

Oregon State, which joined the Ducks in the NCAA tournament, saw three of its players win, with Paul Peterson, Tyler Simpson and Casey King all winning comfortably.

Jonnie Motomochi, who lost to University of Portland golfer Hans Reimers 3 and 1, was the only OSU golfer to lose Wednesday. But OSU assistant coach Tim Sundseth, the runner-up in 2008, gave the Beavers another victory as he defeated Daniel Dyquisto 3 and 2.

In the women's tournament, 2008 champion Kate Hildahl led 2007 winner Kristen Svicarovich for 13 of the first 15 holes, but Svicarovich won the final three holes, making birdie on the par-4 16th and par on the final two holes, to take a 2-up victory.

Svicarovich will meet 2002 winner Kailin Downs in Thursday morning's quarterfinals. Downs, an assistant coach at Oregon State who regained her amateur status after playing professionally, beat Kat Gerrish 7 and 6.
